Chapter 208

Chen Xin finally convinced Qin LAN to agree to stay and take care of her shelter instead of following him to travel thousands of kilometers back home to meet someone.

As for Chen Xin's way of persuading Qin LAN, she naturally saw all kinds of weapons and equipment he had prepared on the tracked armored RV.

Looking at Chen Xin's radar, UAV and heavy machine gun installed in his car, Qin LAN knows that these things are enough for Chen Xin to protect himself along the way. As long as he doesn't go with the army hardtop, ordinary robbers and so on, he can't help his armored car.

The only thing that worries Qin LAN is that Chen Xin is alone. If something happens on the way, she may not be able to deal with it in time.

However, this is not a problem, Qin LAN did not continue to insist on accompany Chen Xin to go this trip, so after Chen Xin put out the weapons on the car, Qin LAN did not continue to struggle.

Moreover, what Chen Xin said is also reasonable. Once he goes there for a month or two, she needs to help Chen Xin look after his home.

With Qin Lan's help and Mo Qingyan and Mo Qingxin's help, Chen Xin has no worries about his home.

Now we just need to upgrade a complete shelter and manufacture the ground source heat pump needed by the municipal government, and then we can start.

In order to prepare for the upgrade, Chen Xin took a bath in the evening and went to bed early so as to give himself a good condition and wait for the upgrade of the refuge after getting up early tomorrow.

Qin LAN has moved to his room, but this evening, no matter he or Qin LAN, they didn't say they wanted to do something intimate. Chen Xin climbed up the upper berth and soon fell asleep.

Qin LAN sleeps in the lower bunk, listening to Chen Xin's even breathing sound in the upper bunk, and soon goes to sleep. However, the corners of her mouth are slightly tilted up, with a satisfied smile on her face.

The next morning, Chen Xinqi got up very early, even earlier than Qin LAN, who always got up early.

After washing and preparing breakfast, Chen Xin shouts Qin LAN.

Ding Ning had to go back to the Municipal Bureau to report the situation yesterday, so he left with them yesterday. Only Qin LAN stayed here because she was still on a convalescent leave.

So there were only two of them for breakfast this morning.

After eating Chen Xin's porridge with minced ham, Qin LAN asked Chen Xin, "ah Xin, you said you would start to transform your home today. How do you plan to start? Is there anything I can do for you? "

"Where to help? There's no place to help. I've finished most of the transformation. The reason why I didn't finish it before is that I just didn't have enough materials. " Chen Xin heard that Qin LAN wanted to help, thought about it and declined her kindness: "now the city government has sent materials, I'm enough alone, a LAN, you have a good rest today."

With that, Chen Xin finished cleaning the table and went to the storeroom alone.

Qin LAN heard that Chen Xin said that he didn't need his own help and didn't ask for it. Instead, he turned on his game console and was ready to have a good rest as Chen Xin said today.

And Chen Xin came to the storeroom, looking at the materials filled with the storeroom, ready to start the overall upgrade of the shelter.

Open the system interface, control the thinking, and focus on the whole refuge. The system interface also shows the option to upgrade the whole refuge.

"Simple shelter"

"upgrade plan 1: upgrade the shelter protection level, enhance the shelter disaster prevention ability, enhance the survival comfort, the shelter overall technology + 1, upgrade the survival 12000"

"upgrade plan 2: expand the shelter living space, increase the shelter capacity, improve the shelter material support ability, the shelter can accommodate people Chen Xin did not adjust the same upgrade plan as before, but he had his own detailed ideas on some details of the overall upgrade of the refuge.

Without too much hesitation, he directly put in all kinds of materials in the storage room and chose two plans to upgrade at the same time. It still takes nearly 3000 points to reduce the survival cost to one tenth, which is two-thirds of the survival cost of Chen's novice. Most of the materials stored in the storage room are directly consumed, leaving only a little bits and pieces.

It can be said that Chen Xin's accumulation over the past six months has been consumed in this upgrade.

But as the green light spreads to every inch in front of him, Chen Xin closes his eyes with a smile of joy and expectation. He wants to open his eyes and see a new refuge.

When he opened his eyes again, the green light had gone, and the shelter had changed.

He is still standing in the storeroom, but this storeroom has become a simple food storeroom, with shelves to store all kinds of food.

Chen Xin looks at the food storeroom as big as the original storeroom, and checks the refrigerator upgraded from the previous food storeroom and refrigerator. Chen Xin nods and leaves the storeroom with satisfaction.After going out of the storeroom, Chen Xin should face the original public space, but now it has been upgraded into a hall.

This is one of the changes made after the overall upgrade of the refuge. Chen Xin changed the original refuge into two floors, with the public space as a hall connecting the upper and lower floors.

The rooms on the first floor are storage room, workroom and infirmary, as well as the power generation area composed of ground source heat pump, algae oxygen generator and power distribution room. The passage connecting the planting greenhouse is also arranged on this floor.

The main body of the second floor is a semi open living room and kitchen, because the public space runs through the upper and lower floors, so one side of the living room is just a structure similar to the balcony, you can directly see the first floor.

There are five double rooms around the living room. Each room has a separate bathroom and bath function. However, Chen Xin has built an independent bathroom on the second floor, which can be regarded as fulfilling his promise to Qin LAN and making a hot spring bath.

Chen Xin didn't go up to the second floor, although as soon as he looked up, he could see Qin LAN sitting in the living room playing games, as if she didn't feel anything.

Turn around and come to the planting greenhouse through the channel connecting the planting greenhouse. There have been earth shaking changes here.

The original square planting greenhouse has become a huge cylindrical structure with a diameter of 15 meters and a height of 20 meters, and the biggest change is not the space of the planting greenhouse, but its internal planting area.

The bottom of the greenhouse has become a one meter deep pool, in which several swimming fish are swimming happily. It seems that Chen Xin was too depressed to raise them in the sink before, but now he finally has enough space to swim.

In addition, the original one layer hydroponic planting plate and soil planting area have also changed into a square hydroponic planting plate with six layers and an area of one hectare, one layer on top of the pool, which is irrigated by the circulation system in the planting greenhouse.

The bottom two layers of planting plates are planted with upland rice before. It seems that there is no big difference, but the rhizome at the bottom is no longer rooted in the soil, but replaced with planting plate and nutrient tank.

On the top four are a quarter of carrots, a quarter of cabbages, a quarter of lettuce, and the remaining quarter of strawberries. The other three are vacant.

These are the crops planted before Chen Xin. Obviously, the system upgrade only changed the structure of the greenhouse and did not affect these crops.

The whole planting greenhouse has now entered the mechanical automation stage. It is more advanced than Chen Xin's previous practice of digging and harvesting the ground by himself.

This is obviously the embodiment of science and technology level + 1 in the overall upgrade.

After checking the planting greenhouse, Chen Xin came to the power generation area again. As the energy supply core of the whole refuge, this area can be regarded as the heart area. Especially after the upgrade, Chen Xin connected the ventilation system of the refuge here, and the whole power generation area became more important.

The power generation area is also a large room. On the floor are four ground source heat pumps and their matching generators. Against the wall are four huge green glass cans, which are algae oxygen generators.

However, after they are upgraded, they not only become larger, but also can be automatically extracted from algal sediments. Even the algae inside have changed to produce ethanol.

Although the output is not high, it can only provide Chen Xin with 100 liters of ethanol a month, but this is very good news. At least the output of the refuge is a new product.

The algal oxygen generator is now connected to the air exchange system, and the oxygen produced by the algal oxygen generator will be directly transported to every corner of the refuge through the ventilation pipe.

As for the power distribution room, it is still a combination of power distribution cabinet and storage battery, but there are three more battery installation positions beside it, which can be used to install the isotope thermoelectric battery used by Chen Xin in armored RV.

Although Chen Xin himself has made isotope thermoelectric batteries, commonly known as nuclear batteries, he has not directly changed the refuge to use nuclear batteries or nuclear reactors for power supply. Instead, he has prepared three isotope thermoelectric batteries as backup power in the power distribution room.

"That's good! In this way, it's different to worry about power failure and lack of oxygen. " Chen Xin nodded his head with satisfaction, although the problem of lack of oxygen and power failure has long been ignored by him.

After looking at the power generation area, Chen Xin took another look at the medical room and the working area. There was no big change in the two. The working area only had a more advanced worktable with various kinds of small lathes and equipment, while the medical room separated a sterile operating room and a ward, which looked more like a small medical station than just a medical room.

These are the main parts of the shelter after the overall upgrade, but Chen Xin knows that in addition to these, the entrance area on the other side of the gate has also changed dramatically. At least he moved the material storage room to the top and turned it into a material warehouse.
